[0028] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] It should be noted that the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] See also Figure 1-7 An embodiment of the proofing room of the present invention shown comprises: a proofing chamber 1, a circulation device 2, a screw conveying tower group 4, a wet air output device 3 and a heat source gas output device 5. The proofing chamber 1 is formed by a top plate and side walls to accommodate pastries.

[0031] A spiral conveyor tower group 4 is arranged in the proofing chamber 1, including a first spiral conveyor tower 41 and a second spiral conveyor tower 42 which are arranged opposite to each other, and the outer edge of each spiral conveyor tower is configured to be open to receive moist and hot air to the greatest extent to facilitate proofing. It is understandable that the present invention does not limit the specific number of spiral conveyor tower groups 4, and those skilled in the art can set two spiral conveyor tower groups 4 or more spiral conveyor tower groups 4 according to the proofing requirements and the size of the proofing chamber 1, and such structural changes still fall within the protection scope of the present invention.

[0032] The front bottom of the first screw conveyor tower 41 is provided with an input channel 43 for conveying the proofed material into the first screw conveyor tower 41, and the rear bottom of the second screw conveyor tower 42 is provided with an output channel 45 for conveying the proofed material to the next process. A transmission channel 44 is also provided between the first screw conveyor tower 41 and the second screw conveyor tower 42, and the transmission channel is provided at the top of the first screw conveyor tower 41 and the second screw conveyor tower 42. A material input port is provided on the side wall of the proofing chamber 1 corresponding to the input channel, and a material output port is provided on the side wall of the proofing chamber 1 corresponding to the output channel, so that continuous cyclic proofing of the pastry can be achieved.

[0033] The heat source gas output device 5 is used to output the heat source gas, which is hot steam in this embodiment, or dry hot air. The humid air output device 3 is used to output humid air, and includes a plurality of humidifying tubes 31 arranged in the proofing chamber 1, and the humidifying tubes 31 are provided with humid air output holes 311. The humidifying tubes 31 and the humid air output device 3 can be connected through a PVC plastic tube 32 passed through the ceiling of the proofing room.

[0034] The circulation device 2 is arranged on the side wall and at a height corresponding to the spiral conveying tower group 4 , so as to respectively connect the heat source gas output device 5 and the wet air output device 3 , thereby adjusting the temperature and humidity of the spiral conveying tower group 4 .

[0035] By completely arranging the circulation device 2 on the side wall and avoiding the top setting, the height of the proofing chamber 1 is maximized, providing space for more pastries to be proofed, so that a large spiral conveyor tower can be accommodated, and the spiral conveyor towers are connected together by conveyor belts. The pastries are input into the spiral conveyor tower through a lower height conveyor belt, and then transferred to the next spiral conveyor tower at a higher point, and then output from the bottom end of the next spiral conveyor tower, which increases the travel of the pastries in the proofing chamber 1, effectively utilizes the space in the proofing chamber 1, and improves the proofing efficiency of the pastries.

[0036] The circulation device 2 includes a circulation fan 22, a first reducing connecting pipe 23, an air duct 24, a second reducing connecting pipe 25 and an air guide plate 26 arranged vertically from top to bottom. The circulation fan 22 is arranged corresponding to the wet air output hole 311 to blow the wet air downward. The diameter of the first reducing connecting pipe 23 gradually increases downward in the vertical direction, so that the wet air diffuses more evenly through the air duct 24. The diameter of the second reducing connecting pipe 25 gradually decreases downward in the vertical direction, so that the gas flow rate increases and the air pressure decreases when flowing through the second reducing pipe, so that it can move downward quickly. The air guide plate 26 is provided with a plurality of output holes in the vertical direction to release the wet air blown out by the circulation fan 22 into the proofing chamber 1.

[0037] The wet air output hole 311 is opened on one side of the humidifying tube 31 and is arranged to avoid the vertical bottom of the humidifying tube 31. The wet air output hole 311 is also movably connected to a cover plate 312 through a damping component, and the cover plate 312 is used to adjust the open area of ​​the wet air output hole 311. In this way, a water storage area is formed inside the humidifying tube 31 below the opening portion to prevent the water formed by the condensed wet air from directly dripping into the proofing chamber 1, and the setting of the cover plate 312 can adjust the open area of ​​the wet air output hole 311, thereby facilitating the adjustment of the wet air output effect.

[0038] In a preferred embodiment, the air duct 24 is a radiator, and the radiator is connected to the heat source gas output device 5 through a heating pipe. When the circulating fan 22 blows the humid air downward, the humid air exchanges heat with the radiator.

[0039] The heat source gas output device 5 includes an input pipe and an output pipe, and the input pipe and the output pipe are connected to the radiator respectively. The heat source gas output by the heat source gas output device 5 exchanges heat with the air in the proofing chamber 1 through the radiator. The heat source gas output device 5 is used to output high-temperature gas, which can be hot steam or dry hot gas, and the wet air output device 3 is used to output normal temperature gas with high humidity. When in working state, the operator can open the heat source gas output device 5 and the wet air output device 3 respectively according to the specific temperature and humidity conditions, so as to control the temperature and humidity in the proofing chamber 1. For example, when heating is required, only the heat source gas output device 5 is opened; when humidification is required, only the wet air output device 3 is opened; and when humidification and heating are required at the same time, the heat source gas output device 5 and the wet air output device 3 are opened at the same time, so as to be blown into the proofing chamber 1 through the gas output port. In this way, temperature and humidity control can be carried out more accurately.

[0040] The radiator includes an enclosed frame 241, a plurality of coils 243 are arranged in the frame 241, the two ends of the coils 243 are respectively connected to the input pipe and the output pipe of the heat source gas output device 5, the coils are provided with a plurality of heat dissipation fins 244, and the gaps 242 between the coils or between the coils and the frame 241 are used to form a channel for the humidified gas to pass through. In this way, when the humid air is output, a part of the residual temperature on the radiator can be taken away, thereby improving the thermal efficiency and not wasting heat.

[0041] In another preferred embodiment, the air duct 24 includes a hot steam output port (not shown in the figure), and the air duct 24 is connected to the heat source gas output device 5, and the heat source gas output device 5 is used to output hot steam. When in working state, when rapid humidification and heating are required, the heat source gas output device 5 and the humid air output device 3 can be opened at the same time, and the hot steam and humid air are mixed in the air duct 24, and enter the air guide plate 26 through the second reducing connecting pipe 25 and then evenly output to the proofing chamber 1, so as to perform proofing on the surface points. This method is more efficient in improving the humidity in the proofing chamber 1. When the temperature reaches or is about to reach the predetermined temperature, it is only necessary to open the humid air output device 3 and close the heat source gas output device 5, so that the humidity in the proofing chamber 1 can be more accurately regulated.

[0042] The bottom end of the air guide plate 26 is also provided with an air guide elbow 27 for changing the blowing direction of the gas to a horizontal direction, thereby providing a guiding effect for the gas at the end of the air guide plate 26, blowing it toward the central part of the proofing chamber 1, and making the gas cover the entire proofing chamber 1 as much as possible.

[0043] The circulation devices 2 are provided in a plurality and are evenly arranged on the opposite inner walls of the proofing chamber 1 , so that gas can be transported from both sides of the proofing chamber 1 to the middle, thereby increasing the range of the dough points in the proofing chamber 1 that can be proofed.

[0044] The wet air output device 3 includes a water tank 30, a gas input port 36 and a wet air output port 37. The wet air output port 37 is connected to the humidifying pipe 31. A plurality of atomizers 33 are arranged in the water tank 30. A driving fan 35 is arranged on the gas input port 36. The driving fan 35 blows air into the water tank 30. Under the action of the atomizer 33, the atomized water and air are mixed to form a gas-liquid mixture, and enter the gas output port through the wet air output port 37. Preferably, the atomizer 33 adopts an ultrasonic vibration atomizer, which can be more finely atomized. A water level controller 34 is also arranged in the water tank 30 to give a reminder alarm when the water volume is insufficient.

[0045] Furthermore, a plurality of cooling air outlets 6 are provided on the inner wall of the proofing chamber 1, and the cooling air outlets 6 are connected to a cooling fan 62 through a cooling air duct 61. The cooling air duct 61 is configured as an independent pipeline, which is used to supplement the air with a lower temperature to cool the proofing chamber 1 when the temperature in the proofing chamber 1 is too high, thereby achieving a more precise temperature control effect. At the same time, because the cooling air outlets 6 are arranged on the side wall of the proofing chamber 1, the space in the proofing chamber 1 is more effectively utilized, avoiding interference with the spiral conveying tower group 4 from the height direction.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
